INCPRO'VED MACHINE FOR THE MANUFACTURE OF ELASTIO ROLLS AND TUBES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all to whom these presents shall come:

Be jit known that I, J onn MOULTON, of Boston, in the countyof Suffolk,and State of Massachusetts, have made aninvention of a new and usefulMachine for the Manufacture of Elastic Rolls or Tubes, for variouspurposes, especially for clothes-wringers; and dohcreby Sued to me onthe 10th day of March, 1868, and the 5th day of May, 1868, respectively,although the machine, in practice, may be found to serve various otheruseful purposes.

"The machine above mentioned, consists, first,-in a frame, suitablyconstructed for holding and rotatinga'metallic shaft, about which theelastic material is wound, and in combining therewith a series ofbunters or hammers, for driving the layers or coils of rubher in'closecontact with each other, as they arelwound about the shaft, themachine'further beingprovided with means for folding the strips ofrubber previous to being wound about the' shaft, and of introducing intothefoldthus formed, a metallic wire or string, in manner and for. thepurpose substantially as hereinafter explained.

In the drawings, ahovementioned as accompanying ard a, is fixed acylindrical box or case, 0, and within such box, and at its inner end,is disposed a circular head or carrier, f, which revolves freelytherein.

This revolving carrier f contains a series of segmental plungers orbunter's,? g g, 850., arranged concentrioally about the axis of thecarrier, and so as to leave a circular opening, h, circumscribed bythem, the shanks of uch hunters extending outward to the rear. part ofthe casee, and with'their, extremities abutting against the face orterminus of a can1-groove, z, madejn the inner end of the said case, aseries of studs, j j, 850., being affixed to each shank, which, byimpinging against the inner side of the said cam-groove, serve toretract the hunters, they are revolved by the carrier f, while the outerextremity of the cam-groove serves to advance the hunters. f

The bunter carrier f is revolved within the case e, by means ofaspur-gear, k, affixed to its outer periphery, and in advance of suchcase, this spur-gear engaging with ,a' twin spur-gear, l, aflixed to ahorizontal driving-shaft, -m, supported within and by the standards aa,this shaft being provided with a suitable pulley for putting it inrotation;

The metallic shaft, upon which the elastic roll or tube is to be formed,is shown at n as having one of its ends-extending loosely in the spaceh, within the hunters, and its opposite end securely held within a chuckor colle't, 0, such chuck being supported, and

so as to revolve, within a sliding carriage, 1), this carriage, in turn,being supported upon the horizontal rods 1) and ll, in such manner as tofreely slide thereon.

The chuck o is provided with a spur-gear, q, for 'glV ing it a rotarymotion, suchgear engaging with a twin gear, 1'. sliding upon thedriving-shaft m, before alluded to, and retained thereon by a spline, s,in a mannerwell known to mechanics, the gear 'I', while serving torotate the gear q, also following the sliding movements of the carriagep. p

' The machinery for feeding the elastic material to the shaft isconstructcdas follows:

:The auxiliary frame 0, before mentioned, is placedat an obtuse angle tothe main frame, and is composed:

of I t jwochucks, t t, united at top by a platform, at, of about halfthe length of such chucks, this platform having disposed upon it two ormore upright twin rollers, v v, &c., placed opposite each other, and a'short distance apart, as shown in the drawings.

A horizontal roller, w or w',-is disposed within the frame 0, and uponopposite sides of the platform u, around which and two other; rollers, xx, disposed at the lower part of the frame 0, two endless bands-orfeeding-aprons, b I), travel, these bands being separated, in advance ofthe roller w, by an intermediate grooved roller, 1 and so disposed, withrespect to'thc rollers, as, when passing between them, to be forcededgewise into an upright position between such rollers.

- A trough, for holding naphtha, or other equivalent liquid, in case itsuse should be deemed necessary, is placed under the roller :12, theobject of the naphtha being to prevent the elastic materials fromadhering to the belts b 11 and for other objects.

The roller w, which is the driving-roller of the feeding-aprons orhands, is revolved by means of a spurgear, z, fixed to its innerextremity, such gear engaging with a second and smaller gear, a,revolving upon a stud, b, fixed to the face of the chuck t, and belowthe gear z.

This last-mentioned gear engages with a pinion, c, fixed to the innerextremity of a shaft, (1 duly sup-' ported by and revolving in the lowerpart of the frame a, the opposite and outer end of this shaft beingprovided with a bevelled gear, e, which engages with another bevelledgear of somewhat smaller size, fixed to the driving-shaft of themachine, as represented in the accompanying drawings.

Furthermore, a friction-chimp, f, is applied to the frame somewhat inadvance of the roller '20, while between such clamp and' roller a guide,a, is applied for the purpose of maintaining the elastic material in thecentre of the roller 10.

The carriage p is advanced toward the box 0 and the hunters by means ofcords, g 5 850., secured to its inner face, and extended about pulleys7:. h, suitably applied to the standard a. of the machine, a weightbeingapplied to the extremity of each cord. Any suitable device, however. maybe mployed for advancing the carriage c. 7

The operation of the above-described machine is as follows:

The shaft, upon which the elastic roll or tube is to be wound or formed,is inserted, nearly its entire length, within the space It, beforementioned, a small hole, i or 2 having been previously made through it,at or near each end, a collar, 7, being formed upon the outer end ofsuch shaft, and in advance of the hole '1 as represented.

A strip of elastic material, of suitable width, is led from a suitablesource, and folded, and introduced be' tween the two endless bands I)If, a metallic wire, If, being passed into the bottom of the fold of theelastic strip, as shown in the drawings, this wire being led through theclamp j", before mentioned, which applies suitable tension to it. Theelastic strip, thus folded, and carrying the wire 7:, is conducted tothe shaft 11, before mentioned, and the extremity of the wire fixed inthe hole i in the shaft, and with the elastic strip abutting edgewiseagainst the collar j of the shaft.

The carriage p is next advanced, until the free extremity of the shaft11- is inserted within the chuck, and tightly fixed therein, and themotive-power of the machine put in motion.

As the shaft a revolves, this elastic strip is wound edgewise about it,while, at the same time, the hunters y g, 860., by the action of thecam-groove, before described, are forced alternately inward, and, bytheir percussive force, serve to compress and condense the folds of theelastic strip tightly together.

As this elastic material. accumulates upon the shaft,

the machine, and subjected to the ordinary vulcanizingprocess, and isthen ready for use. d

I would 'remark that the object in applying the frame 0 to the mainframe, at an obtuse angle with respect to the axis of the roller-slmit,is to insure the winding of the elastic material tightly about suchshaft, before being driven in contact with the next preceding layer uponsuch shaft.

I would also remark that instead of two or more rollers placed oppositeeach other, as shown at e 'v in the drawings, one or more rollers, uponone side only, maybe employed, in connection with a fixed ledge orabutment upon the opposite side.

I claim as my invention- 1. A machine, so constructedand operating as tohold and rotate the roll-shaft, and tocause the elastic material and itsaccompaniments to be wound about such shaft, and condensed or tightlydrwen thereon, for the purpose substantially as before explained.

. 2. As an appurtenance or a part of the above-described machine, adevice for folding and maintaining,

in an upright position, the elastic material as it is fed to the shaft,and also for introducing into the fold of the elastic material ametallic wire or string, for the purpose as before premised anddescribed.

3. For the purpose of condensing the folds of elastic material about theshaft,- and for supporting one end of it in position while winding, thecombination and arrangement of the case 0 with its cam-groove i, and thecircular carrier f with its hunters g g, &c., the whole being arrangedand operating essentially as herein shown and described.

4. In combination with the last-described arrangement of parts, thesliding carriage p, with its shaft, supporting-chuck or bearing 0, suchchuck being applied and operating as before referred to and described.

5. Applying the auxiliary frame 0 to the main fi'ame, at an angle to itslongitudinal axis, in manner and for the purpose as herein shown andexplained.

(3. The combination and arrangement of the endless bands If I) and therollers c o, 830., or their equivalents, for producing the same result,in combination with suitable supporting and feeding-rollers, as and forthe purpose before set forth and exhibited.

- -7. The general combination and arrangement of the hunters l y,- &c.,and the shaft-supporting and operating adjuncts, the sliding carriage p,and the mechanism for folding and wiring the elastic material or strips,the whole operating together to produce results before set forth andexplained.
